The Logan-Albert River system is a significant tidal estuary located south of Brisbane, forming the border between the Gold Coast, Logan City, and Scenic Rim council areas. Its headwaters originate in the protected mountains of the McPherson and Main ranges, including Lamington National Park, which is part of the World Heritage-listed Gondwana Rainforests. The Albert River flows from these headwaters and joins the Logan River approximately 11 kilometres upstream from its mouth, with the combined system discharging into Southern Moreton Bay. The total catchment area spans approximately 3,000 to 3,875 square kilometres, featuring a diverse mix of land uses from protected rainforests and grazing lands to rural residential areas and urban development in the lower reaches. The estuary supports a wide diversity of marine life but faces environmental pressures from population growth, altered flow patterns, and land clearing, which have impacted water quality and habitat.
